Puma (Puma concolor) was feeding on a Rhea (large flightless bird related to Ostrich) carcass. Somewhat unusually for a wild adult Puma, she was eating something she didn’t kill. Here she seems to be conducting an extensive search to determine the owner of the kill. She was very intense throughout the process - perhaps she was wary of the other cat returning or she knew she had broken an unwritten Puma rule.
